The ABB HXR 355LB2 AC Induction Machine is a high-performance industrial motor designed to deliver exceptional performance and reliability. This motor features a rated output of 160 kW and operates at a speed of 2,976 rpm, supplied by a 6,600 V, 3-phase, 50 Hz power supply. It is designed to meet the stringent requirements of industrial applications, ensuring long-lasting performance and minimal maintenance.
The HXR 355LB2 motor is constructed with a B-class temperature rise and an F-class insulation system, ensuring high efficiency and durability. It is protected by an IP 55 enclosure and features an IC 411 cooling method, making it suitable for use in environments with a maximum ambient temperature of 40°C and an altitude of up to 1,000 meters above sea level.
This motor is equipped with standard ball bearings and is designed for clockwise rotation. It includes a standard air-insulated IEC main terminal box and is available in a standard blue color (Munsell 8B 4.5/3.25). The motor also features RTD’s (Pt-100) in the stator windings and antifriction bearings, ensuring precise temperature monitoring.
The HXR 355LB2 motor undergoes rigorous testing, including routine tests according to ABB standard procedures, as well as preliminary final tests such as air gap measurement, high voltage testing, and vibration measurement at no-load. It is also protected with a C3 surface treatment for enhanced corrosion resistance.
